Inspiration and suspense abound in this documentary, which follows brilliant teenagers from around the world as they compete in the Intel International Science and Engineering Fair. Approximately 1,700 finalists from 78 countries and territories vie for the top prize, worth $75,000. The milieu is intense, the stakes are high, and the science prodigies themselves are fascinating. They’re far more intelligent and driven than the average teen, yet their emotional reactions and maturity levels seem to track with other kids their age. They want to change the world, crush their competition, and reap the rewards—and not necessarily in that order—which is great fun to watch. Codirectors Cristina Constantini and Darren Foster keep the action zippy, with a balanced mix of uplifting and surprising moments.
